Recent operational highlights:

On April 4, 2017, RedHill announced that the FDA had granted YELIVA®
Orphan Drug designation for the treatment of cholangiocarcinoma. Orphan Drug designation would allow RedHill to benefit from a seven-year marketing exclusivity period for the indication, if approved, as well as other development incentives to develop YELIVA®
for cholangiocarcinoma. A Phase IIa clinical study with YELIVA®
in patients with advanced, unresectable, intrahepatic and extrahepatic cholangiocarcinoma is planned to be initiated in the third quarter of 2017.

On April 5, 2017, RedHill announced the signing of an exclusive license agreement with Entera Health Inc. ("Entera Health"), granting RedHill the exclusive U.S. rights to EnteraGam®
(serum-derived bovine immunoglobulin/protein isolate, SBI), a commercially-available medical food intended for the dietary management of chronic diarrhea and loose stools, which must be administered under medical supervision. Under the terms of the agreement, RedHill will pay Entera Health royalties based on net sales generated from the sale of EnteraGam®
by RedHill.

On April 13, 2017, RedHill, together with IntelGenx Corp., announced that the Ministry of Health of Luxembourg had granted national marketing authorization for RIZAPORT®
(5 mg and 10 mg), a thin-film for the treatment of acute migraines. The national marketing authorization was granted in Luxembourg on the basis of the European Decentralized Procedure (DCP), in which Luxembourg served as the Concerned Member State. The approval in Luxembourg marked the completion of the current marketing approval process for RIZAPORT®
under the European DCP. The re-submission of the RIZAPORT®
NDA to the FDA is expected in October 2017.

On April 24, 2017, RedHill announced the enrollment of the last patient in the Phase II study with BEKINDA®
12 mg for the treatment of diarrhea-predominant irritable bowel syndrome (IBS-D). On July 17, 2017, RedHill announced that the last patient had completed the treatment course and the last follow-up visit. Top-line results are expected in September 2017. The randomized, double-blind, placebo-controlled Phase II study is evaluating the efficacy and safety of BEKINDA®
12 mg in adults 18 years and older who suffer from IBS-D. The study enrolled 127 subjects at 16 clinical sites in the U.S.

In May 2017, RedHill adopted an Expanded Access Program (EAP), allowing patients with life-threatening diseases potential access to RedHill's investigational new drugs that have not yet received regulatory marketing approval. Expanded access (sometimes referred to as "compassionate use") is possible outside RedHill's clinical trials, under certain eligibility criteria, when a certain investigational new drug is needed to treat life-threatening condition and there is some clinical evidence suggesting that the drug might be effective in that condition. Following the adoption of the program, RedHill continues to receive patient requests to obtain access to investigational drugs. Therefore, subject to evaluation of eligibility and all the necessary regulatory and other approvals, RedHill is likely to provide certain patients with an investigational new drug under the EAP. Further information about RedHill's EAP can be found on the Company's website at: http://www.redhillbio.com/expandedaccess
.

On June 13, 2017, RedHill announced the initiation of the promotion of two gastrointestinal specialty products, Donnatal®
and EnteraGam®
in the U.S. RedHill's U.S. commercial operations, headquartered in Raleigh, NC, include a gastrointestinal-focused sales force of more than 30 sales representatives promoting Donnatal®
and EnteraGam®
in select U.S. territories.

On June 14, 2017, RedHill announced positive top-line results from the Phase III GUARD study with BEKINDA®
(RHB-102) 24 mg for acute gastroenteritis and gastritis. The study successfully met its primary endpoint of efficacy in the treatment of acute gastroenteritis and gastritis. BEKINDA®
24 mg was found to be safe and well tolerated in this indication. The randomized, double-blind, placebo-controlled Phase III GUARD study evaluated the efficacy and safety of BEKINDA®
24 mg in treating acute gastroenteritis and gastritis. 321 adults and children over the age of 12 were enrolled at 21 clinical sites in the U.S. and randomized in a 60:40 ratio to receive either BEKINDA®
24 mg or placebo, respectively. The primary endpoint of the study was the proportion of patients without further vomiting, without rescue medication, and who were not given intravenous hydration from 30 minutes post first dose of the study drug until 24 hours post dose, compared to placebo. A Type B FDA meeting is expected to take place by October 2017. Top-line results indicated that the Phase III GUARD study successfully met its primary endpoint in the Intent to Treat (ITT) population (p = 0.04), despite high positive outcome rate in the placebo arm. BEKINDA®
24 mg improved the efficacy outcome by 21%; 65.6% of BEKINDA®
-treated patients as compared to 54.3% of placebo patients (p = 0.04; n=192 in the BEKINDA®
group and n=129 in the placebo group). Correcting for a randomization error, the difference in effect is greater with 65.8% vs. 53.9% favoring BEKINDA®
24 mg vs. placebo in reaching the primary endpoint of the study (p = 0.03). In per-protocol (PP) analysis of patients who met all protocol entry criteria and for which the diagnosis of gastroenteritis was confirmed (n=177 in the BEKINDA®
group and n=122 in the placebo group), BEKINDA®
24 mg improved the efficacy outcome by 27%; 69.5% of patients in the BEKINDA®
group vs. 54.9% in the placebo group (p = 0.01).

On June 15, 2017, RedHill announced the initiation of the confirmatory Phase III study with RHB-105, newly branded as TALICIA(TM)
, for the treatment of H. pylori
infection (the ERADICATE Hp2 study). The two-arm, randomized, double-blind, active comparator, confirmatory Phase III study is planned to enroll 444 non-investigated dyspepsia patients with confirmed H. pylori
infection in up to 65 clinical sites in the U.S., with a primary endpoint of eradication of H. pylori
infection at 42 through 70 days after initiation of treatment. Subject to a successful outcome and any additional regulatory feedback, the confirmatory Phase III study is expected to complete the package required for a potential U.S. NDA for TALICIA(TM)
.

On July 12, 2017, RedHill announced that the second independent Data and Safety Monitoring Board (DSMB) meeting of the first RHB-104 Phase III study for Crohn's disease (the MAP US study) is expected to convene in late July 2017 and will assess the safety and efficacy of RHB-104 in the first 222 subjects who have completed week 26 assessments. The DSMB meeting will include an interim efficacy analysis and an evaluation of an option for early stop for success for overwhelming efficacy. The DSMB's recommendation is planned to be announced by early August 2017. To date, approximately 300 patients of the planned total of 410 patients have been enrolled in the ongoing Phase III MAP US study.
